This research examined the child, parent, and family conditions under which attachment disorganization was related to both level and change in externalizing behavior during preschool among a community sample. Using the ordinary least squares regression, we found that attachment disorganization at 12 months significantly predicted children's…

This study explored variation in affective and behavioral components of infants' jealousy protests during an eliciting condition in which mother and an experimenter directed differential attention exclusively toward a rival. Variation was examined in relation to child temperamental emotionality, maternal interaction style, and attachment security.…

This longitudinal investigation of 84 infants examined whether the effect of 12-month attachment on 18- and 24-month exploration and sociability with unfamiliar adults varied as a function of newborn irritability. As expected, results revealed an interaction between attachment (secure vs. insecure) and irritability (highly irritable vs. moderately…

Nighttime sleep awakenings and infant and family characteristics were measured longitudinally in more than 1,200 infants when the infants were 6, 15, 24, and 36 months old. By 6 months of age, the majority of children slept through the night, awakening their mothers only about once or twice per week. However, not all children followed this…

A notable omission in studies of developmental links to early nutritional deficiencies is infant attachment. In those few studies investigating associations between infant nutrition and attachment, nutrition was defined solely by physical growth, and infants had moderate-severe growth retardation. In this study, we utilized multiple markers of…

Background and method: The aim of this study was to examine whether a mother's sensitivity towards her one-year-old infant is related to the infant's propensity to engage in "triadic" relations--that is, to orientate to an adult's engagement with objects and events in the world, for example in sharing experiences with an adult. In order to…

Examines the validity of the Strange Situation procedure for Japanese mothers and infants by examining correlates and antecedents of Strange Situation behavior for 60 infants and their mothers. Results suggest that the Strange Situation may not be a valid index of the security of infant-mother attachment in Japan. (SLD)

Findings from a study of 109 Israeli day-care providers suggest that they classify, label, and evaluate infant behavior in the Strange Situation procedure much like attachment theorists do. The relatively independent infants were viewed most positively and most providers preferred to interact with these infants. (SLD)

Infants' differential vocal response (DVR) towards their mother and a female stranger at 3 months of age has been predominantly investigated as an index of early cognitive functioning. The present study explored the relationship between DVR and different infant and mother indicators of the developing relationship quality in a sample of 23…
